Abstract: ABSTRACT OF THE DISCLOSURE          A magnetic tape cassette is provided with a pivotal closure lid pivotably secured to both sides of a casing for movement between a closed position, in which the  front  opening  of  the  casing,  through  which  a magnetic tape is accessible for loading onto a rotary head,  is  covered,  and  an  open  position wherein  the closure lid is pivoted away from said opening to expose the tape while the cassette is in use.   The magnetic tape cassette is also provided with a sliding closure member slidably mounted on the bottom of the casing and cooperative with the aforementioned pivotal closure lid. The sliding closure member is in a closed position while the pivotal closure lid is in its closed position,  in which  it  covers  a  bottom  clearance  through which  a device constituting part of a tape holding system is inserted,  and  in an open position while the pivotal closure  lid  is  in  its  open  position  to  allow  the aforementioned device of  the tape handling system to reach into the casing through the bottom clearance.  A locking lever holds the sliding closure in the current one of its two positions.  The sliding closure holds the pivotal closure closed while in its own closed position.

Abstract: CIRCUIT AND METHOD FOR SPLIT BIAS  ENABLE/INHIBIT MEMORY OPERATION               ABSTRACT OF THE DISCLOSURE A circuit and method for enabling/disabling a differential signal output from a memory device, such as a bipolar static random access memory, is disclosed. A split bias, current steering circuit includes a first differential amplifier for steering a current ID along a first current path when a first selected differential input signal, corresponding to a first logic state, is coupled to a first input terminal of said first differ-ential amplifier; and includes a second differential amplifier for steering current ID along a second current path when a second selected differential input signal, corresponding to a second logic state, is coupled to a second input terminal of said second differential ampli-fier.  An output stage produces a selected logic output signal according to which of said first and second cur-rent paths is selected to steer current ID.  A split bias enable/inhibit stage provides controlled operation of the first and second differential amplifiers.  Cir-cuit operation is inhibited by splitting a bias signal supplied to the differential amplifiers.  When inhibited, the circuit steers current ID along a predetermined one of said first and second current paths.  This produces a corresponding continual predetermined logic output signal without regard to the differential input signal present at the first and second input terminals.  Cir-cuit operation is enabled by balancing the bias signal supplied to the differential amplifiers.  When enabled, both differential amplifiers connected to the output stage are operative.

Abstract: ABSTRACT            The invention relates to a highly immunogenic virus preparation derivedby attenuation employing serial passages in avian cell cultures and six plaque purification steps from a Marek's disease virus strain, belonging to Avian Herpesvirus serotype-1. The original virus strain MDV CVI-988 was recovered from a healthy chicken (Avian Diseases 16: 108-125, 1972). The live purified Marek's disease vaccine so obtained is innocuous for specific pathogen free Rhode Island Red chickens which are highly susceptible for development of Marek's disease tumours. The monovalent virus preparation, according to the invention, demonstrated in comparison with Marek's disease vaccines based on the same strain, currently in use at a lower cell passage level, an improved protective efficacy against challenge infection by two representatives of virulent Marek's disease virus. The monovalent virus preparation, according to the invention, provided significantly better protection than current MDV CV1-988 vaccine to challenge infection with a representative of the group of newly emerging very virulent strains of Marek's disease virus, MDV RB/lB. The monovalent virus preparation, according to the invention, provided significantly better protection than is HVT FC126 vaccine to challenge infection with another representative of the group of very virulent MD viruses, MDV Tun.

Abstract: 22 ABSTRACT OF THE DISCLOSURE The range of objects from a television camera is obtained by projecting a series of patterns of uniquely coded stripes of light onto the objects at an oblique angle to the optical axis of the camera and capturing in the camera the coded light signals reflected by the objects. Through proper selection and scaling of a coordinate system and related coding of the light stripes, the range of the object is determined for each pixel by simply subtracting one coordinate of the pixel from the binary coded light signal reflected into the pixel.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a one-piece coin holder having a main cylindrical wall,an end wall and an opposite open end portion.  The latter permits insertion or egress of a predetermined number of coins into or from the holder.

The latter is made of slightly-extensible material.  The inner diameter of the main wall is greater than the diameter of the coins, but the inner diameter of the bulge is smaller than that of the coins, so that the latter are resiliently retained within the coin holder.  The latter can advanta-geously account for coins of varying thickness, according to their wear condition, while maintaining exactly the same predetermined number of coins.

Abstract: ABSTRACT           Methods and related apparatus are described for determining lithological characteristics, such as forma-tion material type and porosity, of an underground forma-tion by utilizing compressional velocity (Vp) and shear velocity (Vs) data.  One described method utilizes the plotting of Vp and/or Vs versus a Seismic Parameter, such as K/p or the Bulk Velocity, and boundaries of velocity values of certain formation material types to define a field of data points.  By comparing the position of the data points to the boundaries of the formation material types, the formation material type and, later, porosity can be determined.  A method is described for determining the presence of a hydrocarbon gas at a particular location in an underground formation utilizing the above methods.          Also, a method is described for determining Vs from Vp data and obtained ratios of Vp and Vs for at least one formation material type.

Abstract: COMBINATION COLLAR AND MUZZLE HUMANE TRAINING AID            ABSTRACT OF THE DISCLOSURE A combination collar and muzzle is used as a humane method of restraining, controlling, and achieving obedient behavior of animals, dogs in particular.  A collar member or loop encircles the neck immediately behind the ears, and a second loop encircles the upper and lower jaws of the animal to form a type of a figure eight combination collar and muzzle.  The two loops are coupled together with a ring behind the jaw.  The loops are slidably connected so that when a leash is attached to the portion of the muzzle loop extending out from the connecting ring it will slide easily and at the same time will exert a downward pressure on the neck immediately behind the ears.  Pressure is thus simultaneously applied to nerves and muscles tending to control the dog humanely and without choking or applying pressure to the trachea and larynx.  The simultaneous pressure serves to calm and control the dog in a precise and effective manner without injury or choking and achieves precise, active and effective control and calmness without injuring the dog.

Abstract: ABSTRACT A decorative fitting having an internal layer as well as a method of fabricating it are disclosed. Preferably, the color layer is a very thin color wall dimensioned so that when it is viewed at one angle it gives the appearance of being a solid wall, yet when it is viewed at another angle it is substantially trans-parent.  To make the color wall, one preferably forms a frame on a first substantially transparent panel such that the frame projects out from the first panel surface.  One then abuts a second substantially trans-parent panel against the frame so as to form a color material insert cavity point, one injects a flowable colored material/adhesive mixture into the cavity and permits the colored adhesive to harden and bind the panel walls together.  Thereafter, one cuts the trans-parent panels into a multiplicity of handle components by cutting the walls along lines partially transverse to the color layer.  This forms multiple handle com-ponents which are a sandwich of the walls with the color layer in between.
